@goodbyestranger my D1 was a happy beneficiary of your mattress topper intel. It would never have occurred to me to get one if you hadn't recommended it.
She has needed all bedding for her rooms in college, first year rooms (not let for conferences) and 3rd year rooms (very much let to conferences; they have special bedding, mini kettles and hotel style tea/coffee/biscuit trays - all locked up in the scouts cupboard)
She was told room no. & bed size, other info was in the college handbook, rules on fairy lights and other electricals, eg kettles allowed - but must be on a tray - etc. I got a basic JL mattress topper and mattress protector, an all-in-one duvet (no cover, you just wash the whole thing, dries really quickly, she loved this)pillows, and a throw from home.
I sent her a coffee maker in her first term and that was a huge hit. A small Lavazza Modo Mio which takes eco capsules.(JL)
